_Local Treatment for the Prevention and Cure of Mild Cases of Nasal Catarrh and Sore Throat._—The treatment is practically the same. The toilet of the nose and throat should be made at least as often, and at the same time, as that of the teeth; certainly, the first thing on getting up in the morning and again before dressing for dinner. In our seaboard cities and towns, at least, there is a very general predisposition to some degree of congestion of the mucous membrane of the nose and throat. This means an abnormal amount of mucus which collects in the parts during sleep. Again, on coming in from out-of-doors on a windy day a large amount of dust, which means microbes as well, has become lodged in the mucous membranes of the nose and throat. This toilet of the nose and throat is best carried out by means of a nasal spray. The spray apparatus consists of a bottle holding some two ounces, a hard-rubber spray piece, and a bulb with tubing to force the liquid through the spray piece. The tip of the spray should have the form of a cone; this should be introduced into each nostril, the bulb squeezed several times, until the amount of fluid is sufficient to be hawked out, and this process is facilitated by holding the mouth open during the spraying of the nostrils. After the nostrils have been thoroughly cleansed, the throat should be sprayed directly. The liquids used must be bland and unirritating, and only enough should be used at one time to cleanse the parts. There are on the market excellent alkaline and antiseptic tablets; one tablet should be dissolved in a spray-bottle not quite full of water. This solution keeps in perfect condition, and is always ready for use. A solution of boric acid, in the proportion of two teaspoonfuls of boric acid to one pint of water, may also be used.
